(7+5) + 4 •13 - 2.
To solve this expression, we follow the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
First, we perform the operation inside the parentheses:
(7+5) = 12
Now the expression becomes: 12 + 4 • 13 - 2.
Next, we perform the multiplication and division (from left to right):
4 • 13 = 52
Now the expression becomes: 12 + 52 - 2.
Finally, we perform the addition and subtraction (from left to right):
12 + 52 = 64
64 - 2 = 62
Therefore, the expression (7+5) + 4 • 13 - 2 equals 62.
To solve the expression (7+5) + 4 •13 - 2, follow the order of operations which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). Let's break it down step-by-step:
Step 1: Solve the parentheses
(7+5) + 4 • 13 - 2
= 12 + 4 • 13 - 2
Step 2: Compute the multiplication
= 12 + 52 - 2
= 64 - 2
Step 3: Compute the addition and subtraction
= 62
Therefore, the expression (7+5) + 4 • 13 - 2 equals 62.
